WIRE-GLASS-ROLLING APPARATUS.

Specification of Letters Patent.

Patented Jan. 14, 1908.

Application filed April 22. 1907. Serial No. 369670.

T 0 all whom it may concern.

Be it known that I, Axrox MEY R, a citihave invented certain new and useful Improvements in llire-Glass-Rolling Apparatus', of which the following is a full, clear, and

exact description, reference being had to the accompanying drawings, forming part of this specification.

iIy invention relates to that class of glass rolling apparatus utilized for rolling sheets of glass with sheets of wire cloth embedded therein and examples of which are to be found in Letters Patent of the United States issued to me November 28, 1905 and January 23, 1906 and numbered respectively 805,657 and 810,786.

The present invention is in the nature of an improvement upon the apparatus shown and described in said patents and has for its object to improve the raising and lowering mechanism associated with the sheet pressure roll by which the wire cloth is delivered and pressed into the first layer of glass and the wire cloth shearing mechanism.

The present invention also has for its object to provide means for smoothing the surface of the top layer of glass after it is rolled.

Figure I is a side elevation of my improved apparatus. Fig. II is a view partly in end elevation and partly in vertical cross section of the end of my apparatus containing the wire cloth'delivery and pressing mechanism. III is a longitudinal section taken through the parts illustrated in Fig. II. Fig. IV is a vertical section taken on line IV-IY Fig. III.

Referring to the accompanying drawings: 1 designates standards that are arranged in couples and which are adapted to receive the journal boxes of rolls 2 which may be raised and lowered by any suitable means, such as set forth in either of the Letters Patent hereinbefore mentioned.-

3 is a carriage that is adapted to move to and fro upon suit-able track rails beneath the rolls 2 and a remaining roll to be hereinafter mentioned, the said carriage serving to sup port a table 4 on which the glass is rolled.

5 are rackbars carried by the carriage 3 and extending longitudinally thereof, all of said parts having the same utility as corresponding parts in the patents mentioned.

6 designates a pair of standards located at one end of the apparatus and disposed in alinement with the standards 1. These standards are provided with vertical guideways 7 in which are loosely mounted journal boxes 8 that are adapted to be raised and lowered in said guide-ways.

9 is a pressure roll that is provided with spindles journaled in the journal boxes 8 and adapted to be rotated above the table 4 on the carriage 3. The spindles of this pressure roll have fixed to them pinions 11) that are adapted to be placed in mesh with the rack bars 5 in order that they may act to impart rotation to said pressure roll upon reciprocation of the carriage 3.

11 designates-a delivery drum that is carried by a shaft 12 supported by means to be hereinafter mentioned in order that the drum may-be raised and lowered with other parts of the apparatus. The drum 11 serves to deliver wire cloth to the sheet of glass being rolled in order that it may be pressed into saidglass by the pressure roll 9, the wire cloth being referably supported in rolled form by a rod 12 that is mounted in bracket arms 13. supported by the standards 6.

14 is a wire cloth straightening roller susit is passing over the delivery drum 11. R0-

tary motionis imparted to the wire cloth delivery drum by spur wheels 16 arranged in mesh with the pinions 10 on the spindles of the pressure roll 9 and spur wheels 17 carried by the spindles of the delivery drum 11. The spur wheels 16 are carried by a shaft 18 supported by the same members that support the shaft of the delivery drum 11.

19 designates lift rods that are pivotally connected to the journal boxes 8 in which the spindles of the pressure roll 9 are mounted and by which said journal boxes are raised and lowered in the guide-ways T of the standards 6 for the purpose of raising said pressure roll to any desired elevation above the glass receiving table 1 or lowering it to the requisite iosition above the table for operation in ro ling batches of glass placed upon the table and into which the wire cloth is pressed while the table is moving beneath said pressure roll.

20 are segmental gears supported by rods 21 extending across the apparatus and ards 6 at a point adjacent to the wire cloth mounted in the standards 6 and to which the lift rods 19 are pivofally connected at 22.

23 are segmental gear levers. the teeth of whlch are arranged 111 mesh with the teeth of the segmental gears 2!) and which are supported by rods 2% located opposite to said se mental gears. Each gear lever is provided with a lift )in 25. 26 designates 11ft rods in which the shafts 12 and 18 of the delivery drum 11 and the spur wheels 16 are journaled, the said rods including upper members 27 that are pivoted at 28 to their lower members in which said,

shafts are journaled and in the up er ends of which upper members are vertica slots 29 that receive the lift pins 25 of the lever gears 23. connection between the lift rods 26 and the gear levers 23 is to permit vertical movement of said liftrods independently of the lift rods 19 that support the pressure roll 9 for a purpose that will presently be made clear.

30 is a hand lever that is pivotally C0117 nected at 31, see Fig. II, to one of the standards 6 and 32 is a connecting rod pivoted to said hand lever and also to the gear lever 23 whichparts it serves to unite, as seen in thelast mentioned figure and in Fig. III.

33, see Fig. 111, designates a stationary shear bladevthat is supported by the standdelivery drum 11 and adjacent to the path of movement of the wire cloth in its travel from said delivery drumto the pressure roll 9 and the table 4.

34 is-a movable 'shear blade that is an ran ed in opposition to the stationary shear ,bla e and which is adapted to be moved to- 'wards said stationary blade for the pur )ose of severing the wire cloth into sheets 0" desired lengths as it passes over the delivery drum 11:

i at 36.110 the standards 6 and each having one 35 .are bell crank levers pivotally connected of its arms arranged in engagement with the movable shear blade 34 while the other arm of each lever extends into pixtapositlon with the lift rod 26 that is located at the side of the apparatus at which said lever is located.

Each of the lift rods 26 is provided with a stud. or pin 37, see FiglV and dotted lines Fig. III, adapted to engage the adjacent arm nfthe bell crank lever 35 upon each upward movement of said rod for the purpose of actuating the lever and causing it to impart movement to the movable shear blade 34 for The object in making this slot and pin erases positions that they are adapted to be struck by trip blocks 3 carried by the carriage -3, see Fig. II, when said carriage has made a partial forward movement and the shears are to be brought into operation to cut the wire cloth passing between the shear blades. When the trip blocks strike the dogs said dogs are moved in a direction toward the lift arms 39 with the result that the heels of the dogs press against said lift arms and serve to elevate them, whereby the lift rods in turn are caused to actuate the bell crank levers 35 that move the shear blade 34 for cutting action and the wire cloth is severed as desired.

The lift rods 26, 27 being loosely connected to the gear levers 23 by slot and pin connections, said rods may readily move vertically in the wire cloth shearing actions without any movement being imparted to said levers or to the lift rods 19 that support the pressure roll 9 and are adapted to be moved upon the actuation of the gear levers. When it is desired to ele vate the pressure roll 9 and the wire cloth delivery mechanism cooperating with said roll and carried by the lift rods 26, 27 the end lever 30 is depressed, thereby-causing it to exert a pull upon the connecting rod 32. The gear lever 23 is then moved by the con- .necting rod and acts to lift the lift rods 26,

27 and through cooperation with the segment gear 20 causes said segment gear to be moved upwardly, thereby raising the lift rods 19 and the pressure roll and cooperating parts are raised to a desired degree above the table 4. A reverse movement of the levers results in the parts just described being lowered to their former positions or to any degree of elevation that may be desirable.

In rolling sheets of glass in the use of my apparatus a mass of molten glass is first placed upon the table 4 back of the pressure roll 9 and at a point adjacent to that at which the wire cloth passes beneathsaid roll. Then, as the table moves forwardly during the rotation of said. pressure roll which is driven by suitable means and geared to the carriage 3, the molten glass is rolled into a lower layer wit-h the wire cloth embedded therein. A mass of molten glass is placed upon the lower layer of glass and the wire cloth embedded therein and this mass-is rolled into an upper layer by one of .the rolls 2 of the apparatus, thereby molesing the wire cloth within the two layers of glass. The rolling operation is clearlyillustrated in Fig. I of the drawings.

For the purpose of smoothing or ironing out any wrinkles or ridges that may exist at the top surface of the sheet of glass as it is produced I provide an ironing member 43 that'comprises a heavy block or plate, preferably of metal, extending entirely across the s ace occupied by the sheet of glass being rolle and adapted to ride in contact with the upper surface ofsuch sheet This iron ing member is supported at the proper elevation above the table a to contact to the desired degree with the sheet of glass by means of wheels 44 that are journaled, as seen in Fig. I. The table travels freely beneath the ironing member which is main tained in set position adjacent to the roll 2 that produces the final rolling action upon the sheet of glass and the ironing member is held in such position by means of arms or links 45 that are preferably fittedto the spindles of the roll last referred to and are adapted ,to permit a rise and fall motion of the ironing member.
